End Date: May 31, 2014
Genotypes of Solanum chacoense (chc) will be grown under different N regimes in tissue culture and root parameters measured. These same genotypes will be grown in the greenhouse under long- and short-day photoperiods. Plants will be harvested 100 days after planting, and partitioned into above-ground biomass, roots and tubers, and analyzed for total N. The correlation between root parameters from tissue culture plantlets and greenhouse-grown plants will be calculated. Relative response to photoperiod will also be determined as the ratio of roots:tubers produced under short-day to the ratio of roots:tubers produced under long-day growing conditions. Crosses will be made between phu-stn and chc.
